Chromosome 20 is one of the 23 pairs of chromosomes in humans. Chromosome 20 spans around 63 million base pairs (the building material of DNA) and represents between 2 and 2.5 percent of the total DNA in cells. Chromosome 20 was fully sequenced in 2001 and was reported to contain over 59 million base pairs representing 99.4% of the euchromatic DNA.[3] Since then, due to sequencing improvements and fixes, the length of chromosome 20 has been updated to just over 63 million base pairs.[1]
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Depending on the genome annotation used, chromosome 20 contains 897 or 1,068 genes.[4][5]
The following are some of the genes located on chromosome 20:
